(Cl. 1-3) This inventionrelates to a stapling device having a number of novel features. Thenovel features of this invention when collectively employed, areparticularly applicable to that type of stapling device known as astapling plier. These features, however, may also be individuallyemployed.

The stapling device of this invention 'has "a number of specificadvantages over conventional devices, some of which will be brieflyenumerated below: i

(1) The magazine of the device is formed with an openable cover so thatthe staples may be conveniently dropped directly into the magazine andthe follow block is automatically retractable,

(2) The actuator member of the stapling device of this invention ispivotally connected to the magazine and normally overlies the cover,which in turn is also pivotally connected to the magazine. Therefore,the device may be very easily loaded by simplyswinging the actuator awayfrom the cover and thereafter swinging the cover away from the magazine.

(3) The coverof the magazine is of novel construction and is formed witha support portion and a driving portion downwardly movable with respectto said support portion. Between the support portion and the drivingportion a wire spring member is disposed whichis in turn formed with apair of'reverse acute angular-bends therein so as to permit properaction of the parts and, at the same time, permit proper employment-ofthe space provided.

(4) The staple driver of'the instant invention is formed with a holdingportion and an operating portion. These portions are angularly disposedwith respect to one another at an angle less than 180 degrees but morethan 90 degrees so as to permit proper employment of space and effectiveoperation of the device.

Effective means are further provided to secure the stapling driver tothe remainder of the device so as to permit proper employment of theparts.

(6) The construction of the instant application is simple and economicaland can be manufactured with the employment of relatively unskilledlabor.

Other objects and advantages of the instant invention will becomeapparent by a reading of the specification.

The invention may be briefly described as a stapling machine comprisingstaple holding rneans, staple advancing means therewithin, stapledriving means overlying the staple holding means and actuatnig meansoperatively connected to the staple driving means.

In the preferred modification of this invention the staple holding meanscomprise a magazine which is preferably manufactured with alongitudinally disposed rail therewithin, the staple advancing meansconsist of -a follower and spring means connected to the follower and tothe cover. With this construction raising ofthe .cover will cause thefollower to move rearwardly and permit simple loading of the device. Acover is *pivotally connected to the magazine and normally overlies thesame and bears a staple driver at one end thereof. The actuating means,in the preferred modification, consist of an actuator member which ispivotally connected to the magazine and normally overlies the cover. Theactuator and the cover are further provided with complementary latchingmeans. The actuator may be pivoted away from the cover and 'UnitedStates Patent 0 volved in proper relationship.

3,103,012 Patented Sept. 10, 1963 the cover thereafter pivoted away fromthe magazine in order to permit simple loading of the device.

Where the device of the instant invention is made in the form of astapling plier, 'a base and an anvil thereupon are provided. Themagazine is normally spaced from the base. A spring is secured to saidbase and intervenes the magazine and base.

Referring :now to the specific form of the invention herein as set forthin the accompanyingdrawings for a detailed description thereof thestapling device '11 is formed with .a :base 12 having an anvil r 3 0thereupon. Base 12 also bears a pair of upwardly-extending lateralmagazine supporting portions 13 and the forward portions 14-ofmagazinesupport portions 13 are fuurther up wardly extending. A-leaf spring 31is secured to base 12 by rivet 32. 1

A magazine :15 -is -journaled at "the rear of magazine support portions13 of -base I2 and is secured thereto by pin 33. Magazine 15 is openand'has a longitudinally disposedrail :lfiitherewithin. A follower17is-disposed=upon rail '16 and bears a hook portion 18 thereupon. Acoil spring bears an eyelet 19 at one end thereof which is secured toportion 18 of follower 117. A cover 24 normally overlies magazine 15 andis also pivotally disposed withrespect to-rnag-azine 15. Pin 33holds'the parts in- Cover 24 is formed with a support portion 25 and adriving portion '26. A spring 27 is formed with a pair of bifurcatedlateral portions 28 which are connected to one another by transverseconnecting portion 29 located at one end of spring 27. Spring 27 bearsreverse angular I portions 34,35 and 36 which are located intermediatethe end portions of spring 27. Connecting portion 29 of spring 27 bearsagainst the underside driving portion 26 bears laterally disposedextensions 42. Operating portion 1 39 and holding portion 40 of stapledriver 38 are angularly disposed with respect to one another at an angleof less than 180 degrees but more than 90 degrees.

. Extensions 42 of staple driver blade 38 are disposed in slots 43 whichare formed within the forward portion of the driving portion 26 of cover24-. These slots 43 are formed by providing spaced'overhanging portions66 about driving portion 26.

In order to permit driver 38 to be inserted into slots 43 and to be heldin position the upper part of portion 26 adjacent slots 43 is providedwith an additional slot 44.

Support portion 25 of cover 24 bears an arcuate portion 68 whichconstitutes one portion of latching means. Actuator 46 also has lateralportions 67 at its forward end thereof and is pivotally connected toportions 14 of base12. Actuator 46 also bears pin 47 to which roller 45is rotatably connected. Roller 45 constitutes the other portion of thelatching means and normally bears against arcuate portion 68 as shown inFIG. 8.

Cover 24 bears a pair of projections 48 at'itsrear portion thereof whichin turn are adaptedto abut against separable flanges 49 at the rear ofmagazine 15.

the instant invention may now be explained.

The device is loaded with staples by moving cover 24 downwardly in thedirection of the arrow 69 (FIG. 1). This movement causes roller 45 toclear-arcuate portion 68 since arcuate portion 68 moves arcuately anddown wardly as shown in FIG. 8 in the direction of the arrow 70.

Actuator 46 can then be moved pivotally in the direc tion of the arrow71 shown in FIG. 6 to the position shown therein. Cover 24 can then bepivotally moved in the direction of the arrow 72 shovm in FIG. 6 so asto expose magazine 15. The movement of cover 24 to its limit of travelcauses projections 48 to bear against flanges 49 which, since flanges 49are springable, holds cover 24 in openposition. As can be seen from theinstant specification, the pivotal movement of cover 24 also causesfollower 17 to be moved rearwardly against spring 20. Staples arethereafter loaded upon rail 16 and cover 24 pivotally moved to itsnormal position above magazine 15, thus disengaging projections 48 fromflanges 49. It will be noted that this movement causes follower 17 tomove forwardly until stopped by the staples (not shown) now disposedover rail 16. Actuator 46 is then moved to its normal position overcover 24- whereby the complementary portions 47 and 45 mesh together andcause a latching action to occur.

The device'may now be used to apply staples to articles which are placedbetween anvil 30 and the forward portion 50 of magazine 15. Downwardpressure on actuator 46 causes corresponding pressure on spring 31 andthereby brings the forward portion 50 of magazine 15 as close to anvil30 as the material (not shown) disposed between said parts will permit.Further downward pres sure of actuator 46 causes driving portion 26 ofcover 24 to move downwardly in the direction of the arrow'shown in FIG.2. This downward movement compresses spring 27 and causes operatingportion 39 of driving blade 38 to propel a staple (not shown) throughstaple discharge opening 51 in magazine 15, causing stapling to occur.During the downward movement of driving portion 26 of cover 24 supportportion remains in fixed position a-fter magazine 15 abuts anvil a Therelease of pressure on actuator 46 causes pressure to be released onsprings 31 and 27, thereby causing the parts to assume their'normalposition. As is well known inthe art, since follower 17 is springloaded, an additional staple is then placed in position forfurtherdriving.

The parts of the instant invention are'preferably assembled as follows:

Anvil 30 is staked to base 12 at its forward portion thereon. Rivet 32is applied to spring 31 and base 12 so as to rivet the parts intoposition. Pin 47 is placed into position on actuator 46 and actuator 46is thereafter riveted to portions 14 of base '12 by extrusions 52.Follower 17 is then slid on to rail 16. Magazine 15 is then placed intoposition between portions 13 of base 12. Driving portion 26 of cover 24is thereafter obtained and holding portion of staple driver 38 is slidinto position into slots 43. Spring roller 21 is then assembled toportion 26. Spring 27 is then dropped through opening 53 in portion 26with connected portion 29 dropped through first so that connectedportion 29 bears, against the inside of portion 26' Driving portion 26is then slid within support portion 25 and end portion 37 of spring 27is then snapped into position over the upper portion of support portion25 so as to hold the parts in place. The entire assembly of the cover isthen placed between the side portions of magazine 15 and all partssecured together by pin 33. Spring 20 is then disposed over roller 21and secured into position upon hook 23.

The foregoing specific embod-iments of the instant invention as setforth in the specification herein are for illustrative purposes and forpurposes of example only.

Various changes and modifications may obviously be made within thespirit and scope of this invention and would occur to those skilled inthis art.
